INTEGRATED CIRCUIT ACCESS

A method provides access to an integrated circuit which may comprise a storage containing an unalterable first security key and a memory containing a second security key. The method may comprise: - checking the second security key by comparing the first security key and the second security key, - if the second security key is valid, ˆ˜ providing access to the integrated circuit, optionally depending on the validity of an access key, and - if the second security key is invalid, ˆ˜ enabling erasing the memory, and ˆ˜ storing in the memory a new second security key which corresponds to the first security key. Erasing the memory may be followed by checking the erasing for completeness.
